Application led April 24, 1913. Serial No. 763,308.

To all whom, 1 may concern.'

Be it known that I, JOSEPH W. REESE, a citizen of the United States, anda resident of Salt Lake City, in the county of Salt Lake and State ofUtah, have invented a new and useful Improvementv in Clamping Devices,of which the following is a specification. .Y y

My invention is an improvement in clamping devices, and has for itsobject to provide mechanism of the character specified, especiallyadapted for usewith ties other than wooden ties, and wherein means isprovided for holding the rail firmly to its seat on the tie, capable ofbeing released when desired, and withont the use of spikes and the like.

In the drawings z-Figure l is a top plan view of the improved clampingdevice in place, Fig. 2 is a side view of the clamping device, the railand the tie being in section. Fig. 3 is a perspective view of one of theclamps, and 4 is a similar view of the rail seat.

The present embodiment of the invention is shown in connection with atie of metal composed of a base or bottom 1, having transverselyarranged teeth or corrugations for gripping the road bed to preventlongitudinal movement of the tie and having upstanding side walls orflanges 3. The tie is thus of channel shape, and the channel may befilled with concrete or the like plastic material capable of hardeningto make the tie of suicient weight. At the points where the rails crossthe tie, each of the side walls or flanges 3 is extended upwardly andeach of the said extensions is provided with a notch or recess 4, thesaid notch or recess being of a width to receive the base 5 of the railand of a depth approximately equal to that of the rail. The upper edgeslof the side walls of each notch are rounded as indicated at 7, and fromthe said rounded portions, the extensions slope vor incline downwardlytoward the level of the upper edge of the side wall as indicated'at 8.On each side of each notch 4 and at the junction of the edges of theextension with the side wall, the said side wall is provided with anotch or recess 9, each lof the said .notches or recesses inclininginwardly and Adownwardly as shown. It will be understood that 4thenotches 4 of the opposite side walls are in alinement at each end of theti'e and seat is rounded as shown that the rail extends transversely ofthe tle, seating in the said registering notches.

A pair of clamping jaws is provided for each rail, each of the said jaws10 being of a width sufficient to extend from one side wall 3 totheopposite side wall and each of the said jaws is provided at its freeedge with an enlargement 1l, fitting between the base flange 5 and thetread 6 of the rail and engaging the web 12 of the rail to preventmovement of the rail in any direction. The free edge of the saidenlargement 11 is sha ed to fit the web of therail and the un erA faceof the tread and ythe upper face of the adjacent side of the baseflange. At the opposite end of the jaw from the enlargement ll, each ofthe said jaws is proyided with oppositely extending lugs or journal pins13, the said journal pins being adapted to engage the notches 9, at theadjacent side of the rail. It will be understood that the notches 9 oneach side of each rail are in register, and the clamping jaws may beremoved or inserted, by lifting the end of the said jaw remote from theenlargement 11, upwardly and outwardly, to cause the journal pins 13 todisengage from the slots 9.

Each of the clamping jaws is provided with an integral extension 14, atthe end adjacent to the journal pin, each of the said extensionsextending inwardly approximately parallel with the body of the jaw andin downwardly spaced relation and the upper face of each of the saidextensions is provided with a plurality of recesses 15, as indicated inFig. 3.

A rail seat is also provided for each rail, one of the said seats beingshown in Fig. 4. Each of the said rail seats 16 is of a width to fitbetween the side walls 3 of the tie and each seat is provided on itsupper face at the center thereof with a .plane surface 17, upon whichthe base flange 5 of the rail rests, the said plane surface being of awidth corresponding to the width of the base flange. From the planesurface 17 the upper face of each seat inclines downwardly toward theends of the seat as indicated lat 18, and at each E-end the upper faceof the at 19 to ft between the extension 14 and Irlile body 10 pg theadjacent ing 'aw. e portions and 19l of theggtare slhaped to fit theunder faces of the gripping jaws l() smoothly and closely, and thatportion ot' tht` limiet' t'aee ot the seat adjacent to the ends thereofis shaped to roughly tit the upper fare of the extension 14 as indicatedat 2t). The seat is arranged as shown in Fig. Q the ends thereof beingreeeived between the gripping jaws and the extensions, and at eaeh ot'the portions 2t) the seat. is provided with de` pending lugs 2l, thesaid lugsl being shaped to tit the recesses 1.3 and being reeeived inthe said reeesses. lVhen the seat and the jaws are in place. there isjust sutlieient room between the tace 17 ot' the seaty and the underfaces of the inner ends of the gripping jaws to receive the base flangeot the rail. and the said flange is held between the inner ends ot thejaws and the upper' fare ofthe seat.

llaeh extension of eaeh side wall is provided with an opening on eaehside ot' eaeh noteh. each opening being at the rounded portion 7, andthe openings at eaeh :side of eaeh rail register' to reeeive a lorkingpiu QQ. Each ofthe said locking pins extends transversely ot' the tie,above the inner end ot' the adjacent gripping jaw. to prevent upwardmovement of the said jaw, thus loeking the inner end of the jaw to thetie.

The seat 16 is a bridge extending between the extensions 1st of thegripping jaws and seated on the said extensions. The said bridge or.seat not only supports the rail at this point but also absolutelyprevents upY ward movement otb the inner ends ot' the gripping jaws.aeting thus as a loeking member in addition to its funetion as a bridgeand rail seat.

lt will he nottieed from an inspeetiou of Fig. Q that. the rail does nottoueh the tie. the under`faee of the base flange being spared above thebottom walls of the notehes Yt.

The prineipal objeetion to ties ot' metal and eonerete is the lark ofresilieney of the said ties. and attempts have been made to overeoinethis4 disadvz'intage by inserting wooden bloeks. springs or the like.\\'ith the pres-ent eonstruetion however. the rail is supported on a-vielfling seat. lt will be noted that between the .surtaees Qt) on theunder tace of the seat.y the said seat is reeessed or eut awavvtransversely and the .seat is supported at its ends. being` tree intermediate the ends. Thus a eonsiderable degree ot resiliency is imparted tothe seat. Further more s'inee the seat is sujiported on the extensions.and the jaws mav rt el; lightly. a eonsiderable degree ot resilieneyds`obtained. sutlieient to dispense vvith eusbions er springs.

Yhen the loeking pins 2Q are removed. either jaw may be removed. whih`when in plaee.y the said pins prevent areidental diss plaeenient` of thejaws while at the saine time. not intert'ering with the resilieney otthe seat.. r1`he lugs 21 by their engagement with the recesses 15.provide a loek to prevent displaeement of the jaws outward. thuset'leetually providing against aeeidental disA plaeement ot' the seat.1t will be evident also that the greater the weight of the rail the moretightly will the rail be gripped by the jaws.

rt`he improved elaniping deviee will etfeetually hold the rail to theseat without the neeessity ot' wedges. spikes. bolts or the like, and atthe same time the said jaws permit aeeess to the different elements7 torrepairs er the like.
